Question

我使用灯具作为我的测试数据。在我的灯具加载到db之后，但在任何测试运行之前，我需要进行额外的初始化步骤。额外的初始化数据应该可用于所有测试。

test_helper.rb中

class ActiveSupport::TestCase
  fixtures :all
end

user_test.rb

require 'test_helper'
class UserTest < ActiveSupport::TestCase
   test do
     # here I use my extra initialization data
     # it takes a lot of effort to create the data
     # I'd like this data is available to every test in initial state
   end
end

这是日志。我标记了我需要进行初始化的地方。

到目前为止，找到的最佳解决方案是将以下方法添加到ActiveSupport :: TestCase类

def enlist_fixture_connections(*)
  result = super
  # you code here
  result
end

您的代码将在夹具初始化之后和每次测试之前执行，但不会在测试的事务中执行。

如何在加载灯具之后但在第一次测试开始之前运行一段代码？
